WASHINGTON -- New footage released Wednesday of the Asiana Airlines flight that crashed in San Francisco this summer shows the large jetliner pitch up and pivot in the air before bursting into flames.

The footage was released by the National Transportation Safety Board on the same day the agency held a hearing about the effects of automated flights systems on human performance, the training of Asiana pilots, aircraft cabin safety and the emergency response.

Investigators warned the audience before airing the video at the hearing the footage was "potentially disturbing."

The new footage was taken from a fixed security camera and captures the moments before and after Asiana Flight 214 struck a seawall on approach. The jetliner then slammed into the runway, severing its tail section and scattering wreckage across the pavement. The July 6 crash killed three passengers and injured 180.

The initial investigation indicated the pilots failed to maintain the minimum speed and altitude required for a safe landing.

Lee Kang Kuk, 46, who was landing at the airport for the first time, told NTSB officials in an interview the visual approach was difficult to perform in the large Boeing 777 because the runway's light system that helps guide pilots was out of service.

Though Lee said he thought the automatic throttles were working, investigators found the device had been shifted from "thrust" mode to "hold" mode during the approach and no longer controlled the airspeed.
